A solution must be at a lower temperature than a pure solvent to freeze.
Freezing point depression in chemistry is the phenomenon where the freezing point of a solution is lower than that of the pure solvent. This occurs when a solute is added to a solvent, disrupting the solvent's ability to form solid crystals. As a result, the solution needs to be cooled to a lower temperature in order to freeze. This affects the properties of the solution by changing its physical state and altering its freezing behavior.
The presence of a nonvolatile solute in an aqueous solution lowers the vapor pressure of the solution, raising its boiling point and lowering its freezing point compared to the pure solvent. This occurs due to the solute molecules occupying space at the surface of the solution, reducing the number of solvent molecules escaping into the vapor phase. As a result, a higher temperature is needed to reach the same vapor pressure as the pure solvent for boiling, and a lower temperature is needed for the solution to freeze.
When a solute is dissolved in a solvent, the solute particles spread out and become evenly distributed throughout the solvent, leading to a homogenous mixture called a solution. This process is driven by interactions between the solute and solvent molecules, which help to overcome the attractive forces holding the solute particles together.
actually its freezing point depends on the molality of the brine. it is mathematically given as:- Δt=km, where Δt=change in freezing point k= cryoscopic constant m= molality of the substance the value of k for water(as a solvent)is= 1.86 Kg/mole therefore, t=273.15-(1.86*m) where t is the freezing point of brine note:- adding any solute always lower the boiling point of the solution. thnx for asking.
A 0.5 M sodium hydroxide solution will freeze at approximately 12.9 degrees Celsius (55.2 degrees Fahrenheit), which is the normal freezing point of a 0.5 M NaOH solution.
No, adding a solvent to water typically lowers the freezing point of the solution, causing it to freeze at a lower temperature than pure water.
Yes, this phenomenon is called freezing-point depression .

Adding solute molecules such as salt or sugar to a solvent like water will lower the freezing point of the solution compared to the pure solvent. This occurs because the presence of these solute molecules disrupts the regular arrangement of solvent molecules, making it more difficult for the solvent to freeze.
Yes, salt water does indeed freeze. The addition of a solute (salt in this case) to a solvent (water) will always lower the solution's freezing point. This just means it needs to be colder than 32oC to freeze the salt water.
The solvent, water for example, could freeze solid.

The implementation of the contact solution freeze is scheduled for next month.
